Liouville Numbers

I am trying to prove that e and are not Liouville numbers using Continued Fractions, does anybody know an easy argument of doing this...

And does any body have an easy way of showing that Liouville Numbers form a strict subset of Transcendental Number

I know that Any Liouville number must have unbounded partial quotients in its continued fraction expansion. However anybody of a transcendental number that has bounded partial quotients.
Links to Resources on these will be appreciated.
